摘　　要：为摸清肥城采煤塌陷区的发展变化规律,利用航天遥感技术的优势进行采煤塌陷区动态变化调查。首先依据调查区的实际情况选择了多时相的TM及2006年SPOT5数据,并对其进行图像处理;鉴于地物光谱特征作了相关性分析,确定了最佳波段组合;利用ENVI软件对塌陷区的信息进行了计算机自动提取,然后把3个时相的遥感解译成果进行叠加对比分析,总结了塌陷区的变化特征。为矿区的可持续发展提供决策支持,为下一步的地质灾害治理提供依据。In order to find out the development law of coal mining subsidence area in Feicheng city,by using astronautics remote sensing technology,dynamic change of coal mining subsidence area is surveyed.First,based on actual situation in investigation area,selected the datas of TM and SPOT-5 in 2006 in different times,relative images conduction has been carried out.On the basis of spectral characteristics of surface substance,correlation analysis is carried out,and the best band combinations are determined.By using ENVI software,information of subsidence area is automatically extracted by computer.Then three interpretation results（1996,2002,2006） of remote sensing are compared,and characteristics of changes in subsidence area are summarizd.The research result can provide decision support for sustainable development in mine area and can also provide the basis for geological disasters management.
